Laboratory Investigation Of Containment In Underground Nuclear Tests.

Abstract

In support of the DNA program for stemming and containment of underground nuclear tests, existing laboratory techniques were further developed and applied to investigate the mechanics of containing gases in cavities formed by underground nuclear explosions. The experimental procedure includes constant flow rate hydrofracture from a central exploded cavity in an externally pressurized grout sphere simulating a geologic material subjected to overburden. The experiments provide hydrofracture records consisting of the time history of cavity pressure as fluid is pumped into the cavity. Hydrofracture records for exploded cavities, which have a surrounding residual stress field, are compared with those for unexploded cavities, which have no residual stress field, to assess the potential benefit to containment of the residual stress field.
